The answer to 'difference between whole house generator and portable generator' is that a whole house generator is a permanently installed, automatic backup power system that provides electricity to an entire home during a power outage, while a portable generator is a mobile, gas-powered unit that can be used to power specific appliances or devices. Whole house generators are hardwired into a home's electrical system, start automatically when the power goes out, and can run for an extended period, while portable generators are manually operated and typically used for temporary, limited power needs.
Whole house generators are more expensive to purchase and install, but provide more comprehensive backup power. Portable generators are less expensive upfront, but require manual operation and can only power a limited number of items at once. The choice between the two depends on a homeowner's specific power needs, budget, and preference for automatic or manual operation.
